Which method is often employed to safeguard data in transit?

The method commonly used to safeguard data in transit is through the application of encryption protocols such as SSL (Secure Sockets Layer) and TLS (Transport Layer Security). These protocols provide a secure channel over the internet by encrypting the information exchanged between a client and a server. This encryption ensures that even if the data is intercepted during transmission, it remains unreadable and protected from unauthorized access.

SSL/TLS works by establishing a secure session through a handshake process that authenticates the communicating parties and negotiates encryption algorithms. This is crucial for protecting sensitive information such as personal data, payment details, and confidential communications while they are transmitted across potentially insecure networks, such as the internet.

In contrast, methods such as data fragmentation, compression techniques, and data minimization do not specifically address the vulnerability of data in transit. Data fragmentation may improve data transmission efficiency but does not inherently secure the data against interception. Compression techniques reduce the size of the data for efficient transfer but do not provide encryption or security. Data minimization focuses on reducing the quantity of data collected, which is more related to privacy concerns rather than securing data during transmission.
